LOUIS J. DITTMAR, OF LOUISVILLE, KENTUCKY.

CHANGE -MAKING MACHINE.

To all whom it may concern:

Be it known that 1, Louis J. DITTMAR, citizen of the United States, residing at Louisville, county of Jefferson, and State of Kentucky, haveinvented certain new and useful Improvements in Change Vlaking Machines, of which the following is a s ecifi cation, reference being had therein to t e accom anying drawing.

T is invention relates to a change making machine, and particularly to a structure adapted to deliver a plurality of coins automatically operated by the introduction of a coin of greater value.

The invention has for an object to provide a pluralit of delivery chutes adapted to be controlle by a unitary device which is disposed in the path of the coin inlet chute to be operated by coin assing therethrough for the simultaneous elivery of a number of coins from the delivery chute and to be automatically restored to its initial position.

A further object of the invention is to providemeans for controlling the delivery of one or-more of the delivery chutes so that upon the introduction of a coin of fixed value a re'ater or smaller number ofcoins may be de ivered therefrom.

Other and furtherobjects and advantages of the invention will be hereinafter fully set forth and the novel features thereof defined by the appended claims.

In the drawing :Figure 1 is a front elevation with the casing removed; Fig. 2 is a side elevation with the casing removed; Fig. 3 is a horizontal section on the line 3'3, Fig. 1; Fig. 4 is a detail perspective of the delivery lever and retaining plate carried thereby; Fig. 5 is a section on line 55, Fig. 2; and Fig. 6 is a detail plan of the chute controlling device. 7

Like numerals refer to like parts in the several views of the drawing The numeral 10 designates a casing which may be of any desired material or configuration adapted to receive the mechanism car-,

ried thereby. This casing is provided with a series of parallel delivery chutes 11, any desired number thereof being provided and disposed so as to deliver at the front of the machine. This may be advantageously ef- Specification of Letters Patent. Application filed. May 2'7, 1908. Serial No. 435,361.

fected and the coins or articles in the chutes removed from the lower ends thereof by means of the angularly deflected portion 12 at the lower end of the chutes, this portion being cut away or recessed at 13 to ermit the free operation of the retaining carried by the delivery lever '15. T e plate 14 is normally in engagement with the coins in each of the series of chutes, and when the inner end thereof is disposed in the dotted line position shown in Fig. 2 the lower series of coins is released and the plate thrown into the ath of travel whic are thus held until the lever is restored to its initial position by means of the tension spring 16 which extends from the angular arm 17 thereof to a fixed point upon .the casing. This lever is supported in any desired manner, for instance by means of the standards 18 whichform a pivot bearing therefor, and the angularly dis osed operat ing end of the lever is provide with a contact plate19 disposed beneath the coin inlet chute 20.

For the purpose of determining how many of the series of the delivery chutes shall be operable upon the introduction of a sin le coin a controlling device 21 is provided, "or, instance a flat spring locatedin a casing 31 which is mounted at anangle to the chutes upon one of the standards 18. The spring is adapted to be extended across the face'of one or more of the delivery tension to revent the coin therein froni being released in the operation of the) plate 14.

The coin inlet chute 20 is rovided at its up er end with the usual in ct opening 22 an immediatel adjacent thereto the central portion of t e lower wall of the chute 20 plate 14 of the next seriesthereof chutes under is removed and communicates with a dis- 20 a flange 24 is provided upon which a coin of proper size rests, while a coin of less diameter falls into the discharge chute 23 and is delivered from the lower end 25 thereof into contact with a bell or other alarm as indicated at 26. The discharge chute 23' is deflected laterally from the'path of the inlet chute 20 so as to prevent interference with the operating lever 15 and the contact plate 19 thereof;

chutes. k The gipparatus may be constructedand arrange or operation by coins-of any de- From the foregoing description the operation of the invention will be clearly under stood, and it will be seen therefrom that upon the introduction of a coin of proper denomination the delivery lever will be operated to oscillate the retaining plate permitting the dischar e of coins of smaller denomination from a trolled or closed by the slide.

The invention is adapted for use in the sale of papers so that upon the introduction of a five cent piece four pennies may be obtained in change if the price of the paper be one cent, or if the price of the paper be two or three cents a corresponding number of the delivery chutes will be closed by the slide so as to deliverto the purchaser the difl'erence in change between the coin introduced and the cost of the paper or other article sold. While the invention has been described in this connection it is. adapted for any desired use either alone orvassociated withan article delivery device to be operated therewith. If the proper. coin is not 1n- ,troduced in to the coin inlet chute it falls to the discharge chute and after soundingthe alarm fails to operate the mechanism of the machine, while the weight of the roper coin counterbalances the s ring-of t e delivery lever' and operates the plate carried thereby 'sa'id'spring restoring the lever to its initial osition immediately that the coin. falls there om into the base of the receptacle or casing. The: construction and arrangement ofthe series: of delivery chutes-provides for the movement of the-coins on edge thus preventing clog ing, while the angular disposition relieves t e lowermost coins of the direct weight of thoseabo-ve them in the mination for the delivery of chan e or other articles "to be delivered from the c utes as before described.
